I have seen that picture but my understanding is the symbol is just for decoration and has no real meaning as far as they could have easily replaced that with anything. It has Indian (Eastern) origins and they still use it without the negative connotation the Nazis gave it. But even in that case it is not a religious symbol to Indians and is kind of like many other celebratory customs. We still see it used today at Indian wedding ceremonies but like i said i am not aware of any religious meaning associated with it. I am sure you know more about this than i do though and i can be wrong.
